Sue Howlett Swim School
PROJECT OVERVIEW
Sue Howlett Swim School is an indoor purpose built swim school consisting of two pools in Loganholme, south of Brisbane. Sue Howlett Swim School averages up to 1200 bathers per week and is one of the preferred swim schools in the area due to the unique instructional technique that Sue has implemented. With her growing customer base, Sue’s traditional sanitation system was no longer suitable and struggled to keep up with demand. As a result, Sue wanted to improve the condition of her water therefore decided to call Ozone1 and invest in a system that she was confident would give her the best water quality possible and ensure the health and wellbeing of her staff and patrons alike.
OUTCOME
After the Ozone1 installation Sue’s water quality became the best it had ever been and continues to impress her patrons and staff. Sue noticed an immediate improvement in water clarity and as her combined chlorine levels are now maintained and stable at 0.3ppm and below (this is well below the legal safe limit of 1.0ppm combined chlorine) her staff and customers are no longer dealing with chlorine odours and eye/skin complaints.
| Pre Ozone 1 | Post Ozone 1 | |
|---|---|---|
| Free Chlorine | 3.0 ppm | 1.2 ppm |
| Total Chlorine | 5.0 ppm | 1.4 ppm |
| Combined Chlorine | 2.0 ppm | 0.2 ppm |
| pH | 7.4 | 7.2 |
METHOD OF SOLUTION
Primary Disinfection: Ozone1’s Hydroguard 302 Blue I DPD1 & DPD3 smart controller was utilised to ensure consistent levels of Primary Sanitation (Free Chlorine & pH). Secondary Disinfection: Ozone1’s Proprietary System Calculation was utilised for the CO2 along with our unique Advanced Oxidation Process, Ozone + UV (AOP) as a secondary disinfection system, which was designed and built especially to combat Sue Howlett’s combined chlorine and in particular her Monochloramine issues.
The Hydroguard Blue I controllers use a colorimetric DPD method to determine the Free Chlorine & Total Chlorine measurements as opposed to relying on traditional ORP or Free Chlorine sensors. As a result, the outcome is extremely consistent sanitation (Chlorine & pH) levels. The ‘Blue I‘ conducts a DPD1 & DPD3 test every ten minutes, and each and every test can be uploaded via our “Remote Monitoring” to the Cloud and is stored for 2 years, which serves as valuable evidence to satisfy a possible complaint. The remote monitoring also allows access to view their water quality at all times and if set points aren’t met, alerts are sent to the appropriate personnel via text message or email.

TESTIMONIAL
I have been in the Swim School industry for 33 years and in my current location for the past 20 years. During this time I have struggled, like most operators, to keep my combined chlorine levels within range given my bather load. After installing an Ozone 1 system through Brauer Industries this has all changed. The system does what is promised. My combined chlorine levels are now well under the required levels. My staff now have a very comfortable environment to work in. I now have peace of mind knowing that my water is of a very high standard. Thank you to David Brauer and his team for their very professional service before, during and after installation. Sue Howlett Owner Sue Howlett Swim School
